Column with Copper Wire Braided
Column with Copper Wire Braided
Introduction:
Column with copper wire braided is precisely formed by braiding multiple strands of high-purity copper wires, creating an interconnection structure with macroscopic flexibility. This product utilizes the micro-sliding and overall deformation capabilities among the multiple copper wires to achieve gradient dispersion and uniform release of stress, providing an effective solution to the thermal-mechanical mismatch problem between large-sized ceramic packages and organic substrates.

Column with copper wire braided is precisely formed by braiding multiple strands of high-purity copper wires, creating an interconnection structure with macroscopic flexibility. This product utilizes the micro-sliding and overall deformation capabilities among the multiple copper wires to achieve gradient dispersion and uniform release of stress, providing an effective solution to the thermal-mechanical mismatch problem between large-sized ceramic packages and organic substrates.
Advantages
01
Multi-strand braided flexible structure
Braided independent copper wires give the column excellent compliance and ductility for controlled bending and stretch under load.
02
Uniform stress-dispersion mechanism
External loads are shared across strands over a larger area, effectively avoiding early failure from local stress concentration.
03
Outstanding fatigue resistance
Under repeated thermal cycling, the braid distributes plastic strain evenly and markedly slows crack initiation and growth.
04
Suited to large-format packages
Flexibility makes it especially suitable for large CCGA devices, compensating CTE mismatch displacement between substrate and ceramic carrier.
